Arbres sensoriels

L’arbre sensoriel a pour objectif de présenter la diversité des matières plastiques par thématique. Il est entièrement démontable et modulaire composé d’un ensemble de 7 branches avec au total 49 GEM® et transportable dans son packaging.

Vous avez la possibilité d’acheter ou de louer un ou plusieurs arbres sensoriels. Ils pourront par exemple être installés dans votre hall d’accueil ou votre salle de réunion afin de toucher, voir, sentir et comparer les matériaux grâce à un échantillon européen : le GEM®

 Un arbre sensoriel comprend :

  • 1 socle PMMA noir
  • 1 tube central avec un blocage par vis six pans
  • 1 vis de fixation
  • 1 collecteur avec 7 embouts noirs
  • 7 tubes PMMA pour la réception des branches
  • 7 branches inférieures en fibres de verre
  • 7 branches supérieures avec embouts PMMA transparents
  • 7 pièces de fixations par branches soit 49 pièces mâles et femelles
  • 1 kit de pièces de rechange
  • 1 packaging noir 
  • 7 supports translucides pour les fiches d’informations correspondant aux thématiques 



  • The bi-injection process makes it possible to obtain a product combining two materials in a single cycle. The aim is to reduce costs by decreasing the number of operations like assembly, bonding. This technique enables to get a combination of effects: colour, touch, softness, stiffness of structure, transparency, waterproofness, skin effect...

  • Plastics named "bio-based" are made from renewable raw materials (ex: sugar, starch, and cellulose derivative). Bio-based plastics are divided in two categories: conventional polymers which have the same structure and the same technical properties as plastics from oil products (PE or PA from sugarcane ...) and new polymers which have an innovative structure with new functionalities (PLA from starch ...).

  • Adding fillers to plastics makes it possible to change the mechanical, electrical or thermal properties, to improve the surface quality or to reduce the total cost of the material. These fillers are classified according to their nature (organic, inorganic, vegetal …) and their geometry (fibres, beads, plates ...). Examples of fillers are glass, carbon, chalk or metal. These materials (PP, PA, PVC ...) can be used in various sectors such as automotive, aeronautics or electronics industries.

  • A plastic may either be dyed in the mass or dyed with colorants. Colorants can be in three forms: liquid, powder or masterbatch. Masterbatches are the most currently used method. It consists in dispersing high pigments in a resin made of polymer. During this process, the masterbatch is mixed with the natural resin in a precise predefined quantity in order to get the expected color.

  • Special plastics offer new possibilities through the addition of pigments or fillers bringing sophistication to the plastics. They make them olfactory, thermochromic, photoluminescent or magnetisable. It is also possible to imitate other materials such as metal or wood (its weight, noise or touch). These pigments are integrated in masterbatches and mixed with a natural resin.

  • Some products or plastics can be recycled, it provides raw material to be used in the manufacture of new parts. Currently, recycling exists for commodity materials (PET, PP, PVC ...), and tends to develop. The use of recycled plastics can reduce the carbon footprint by decreasing the use of non-renewable resources like oil. Saving fossil resources also avoids emissions (gas, waste ...) of petrol refining.

  • A material is called flexible when it has an elastic character, which means an ability to deform itself. This is defined by measuring the hardness expressed as Shore A or D (0 ShA to 75 ShD).
    Thermoplastic elastomers (TPE) are flexible materials and can be block copolymers (TPA, TPC, TPS and TPU) or polymer blends (TPO or TPV). They combine the elastic properties of rubber with the possibilities of thermoplastic processing (transformation, recyclability, decoration ...).

  • Companies are increasingly faced with brand protection, product security, counterfeiting protection and product authentication.
    One method is the addition of unique pigments, taggants, markers in the plastic which enable to identify, authenticate or expertise the final product by using special analysis techniques. These additives have no influence on the aspect or the final properties of products. Other technologies are for example the laser engraving of a code (datamatrix) on transparent plastics or the extraction of a “signature” at the core of the object, which uniquely identigy it.

  • Transparency is the capacity of a material to let light pass through without distortion. Generally, plastics with amorphous structure are transparent (ABS, PC, PS, PMMA ...). These materials are used in electrical goods, optical, automotive, packaging industries... Materials that let pass little light are translucent (difficult to read a text through it...).
